"Aaron is taking a few days off from the show," John Capo, a rep for the production, told E! News. "His Fantasticks family loves him and offers him support and prayers during this difficult time."

Meanwhile, brother Nick will be back on tour with the Backstreet Boys in April and plans to dedicate the rest of his own tour to his sister.

"Nick Carter is thankful to the many people and the fans who have shared their wishes and prayers during this tragic time," his publicist, Jack Ketsoyan, told E! News. "We want to let the fans know the tour will go on as promised."

"Performing is cathartic to me, and I am dedicating the rest of my tour to my sister since she loved to watch me perform," Nick said.

Meanwhile, E! News also learned that Leslie's body is under examination at the Erie County Medical Examiner's Office in upstate New York. A source said that her death is just as "mysterious" to the Carter family as everyone else.
